The top section is completely seperate from the bottom, so all my rads, pumps, and PSUs stay in the bottom leaving only the hardware on top.

I had planned to get a second Chenming server tower to run them attached like you are when i saw it pop up on another forum.

You were definitely in the right place at the right time for that one, congratulations Puck!

looks really good, a fair amount of modification when into building the TEC assemblies in to the case. it looks like the front two TEC assemblies are venting out the front of the PC case, how is the rear TEC assembly, the one behind the reservoir going to vent the hot air out of the case?

It is venting out the side of the case one of the pictures shows how it was setup, I cut a hole into the side panel for it to vent out through.

The great thing about the case is the front and rear panels would interchange with each other so that gave th the option of modding the panel to suit my needs.

The front side panel has a 200mm fan in it and as most side panel pre-moddified cases it was in the wrong place for my needs, plus it sticks into the case an inch and a quarter right where I needed to mount the reservoir.

Being able to use the flat rear panel on the front of the case solved a multitude of problems.

ok, so the picture with the fan on the side of the case. the ablility to change what side the the panels go on, well if it was like a case i had, when i did that, the reversed panel would slide from the front of the PC case rather than the back. i think with your PC case, what you are saying that your side panels can slide into place even if there upside down?

Yes that is correct!

Starting this post with a cheese eating grin! biggrin.gif

The difference between the old setup and this one is the 3rd TEC assembly was mounted outside on the output line going to the CPU, with this new setup the 3rd TEC assembly is setup before the reservoir.

Previously only 2 of the TEC assemblies were actually dumping cold directly into the insulated reservoir.

Meaning now all the TECs dump their cold into the reservoir in series flow, the reservoir feeds the pump and the output from the pump goes straight to the CPU then returns through the chain of TECs back to the insulated reservoir.

This morning I ran some stress tests on the 3770K at 5ghz, Intel Burn Test with Hyper Threading enabled highest core reached 75c, with Hyper Threading disabled the highest core reached 72c.

Here comes the cheese eating grin:

I ran P95 vs 26.6 and started running P95 at a 9.2c coolant temperature which means the 3rd TEC assembly was not powered up, it's relay is set to power the TEC at 10c and shut off at 8.9c.

Eventually P95 warmed the coolant to reach 10c and the 3rd TEC powered up, it actually dropped the coolant temperature back to 8.9c and shut off with P95 running!

Highest P95 core temperature was 61c.

The second difference is twice the reservoirs insulation from the previous setup, same exact reservoir just twice the insulation.

Previously when I shut down the system and it set overnight when I powered it up in the morning the coolant temperature was the same as the ambient room temperature.

Now the coolant temperature is about 4c lower than ambient over the same time period of being powered down, so when I boot up the system now it is actually booting below ambient.

I am considering adding another 1/2" layer of the foam insulation kinda like wearing a jacket around the reservoir and see what that does, just out of curiosity.

The 3rd difference is much more dedicated fresh air input being supplied directly to the heat pipe coolers.

With the larger area inside the case there is much more fan intake and it is all being fed into the case from the rear and so far it seems to be sufficient air flow.

so, is that little 120 radiator cooling the GTX1080 video card?
if so, what kind of temps does it provide, i know the 1080's dont get all that hot, but still i am curious.

That's not a 120 radiator that's a single 180 Monsta, and the highest load temperature of the GTX 1080 so far was 34c.
